EASA AD 2022-0210
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2022-0210 is an amendment concerning Rolls-Royce Trent 1000 series engines, including models Trent 1000-A2 through Trent 1000-L2. It mandates updated maintenance tasks and life limits as specified in the Rolls-Royce Trent 1000 Time Limits Manual Revision 24. The directive ensures continued airworthiness by requiring operators to comply with the revised maintenance program.
What Changed
This amendment supersedes the previous AD 2020-0241 and introduces new and more restrictive maintenance tasks and life limits for critical engine parts. It updates declared lives of certain components, revises Direct Accumulation Counting data files, and adds new inspections in the Time Limits Manual. These changes reflect the latest safety and reliability data from Rolls-Royce.
Why It Matters
Compliance with this AD is mandatory to maintain the airworthiness of affected Trent 1000 engines, preventing unsafe conditions due to component failure. Operators and maintenance organizations must update their maintenance programs to incorporate these revised limits and tasks to avoid regulatory non-compliance and potential safety risks. The directive streamlines record-keeping by allowing AMP revisions to demonstrate compliance.
What To Do
Operators must replace components before exceeding new life limits and perform all maintenance tasks within specified intervals as per the updated Time Limits Manual. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date, 31 October 2022, to include these changes. Any discrepancies found during maintenance require corrective actions according to Rolls-Royce approved documentation before the next flight or within specified times.
